Crankshaft position sensor

it has a distributor does not have one.

Thanks HMAC300,
If it does not have one why would the part store try to sell me one? also Ford told me they quit carrying them for this year truck. I am confused.
The problem with my truck if it sit's for a few hours it will crank but it is hard to start. I have replaced both fuel pumps, ignition module, throttle sensor, replaced spark plug wires and distributor also the coolant sensor.
so any input on why it is hard to start after sitting for a few hours?

scan for codes and check fuel pressure with a gauge it may be a line clogged try to check when it is hot and hard to start. or it may be the valve is not working correctly between the tanks. see pictures. Auto parts just sell parts nothing else never take much advise from them. Ford no longer carries parts after a vehicle is ten years old.

Thanks I will try this.
